Write a method called clump that accepts an ArrayList of strings as a parameter and replaces each pair of strings with a single string that consists of the two original strings in parentheses separated by a space. If the list is of odd length, the final element is unchanged. For example, suppose that a list contains ["four", "score", "and", "seven", "years", "ago", "our" ]. Your method should change the list to store ["(four score)", ("and seven"), ("years ago"), "our"].
public static void clump(ArrayList strList)
{
for(int i = 0; i < strList.size() - 1; i++)
{
String newStr = "(" + strList.get(i) + " "
+ strList.get(i + 1) + ")";
strList.set(i, newStr);
strList.remove(i + 1);
}
}
